Supergirl, while initially starting off with strong ratings on CBS, has been steadily declining in viewers over time, with its low number of views and hefty $3 million per-episode price tag contributing to Warner Bros. decision to move its female driven superhero show to the younger skewing network.

With The CW picking up the show, it now has four DC superhero shows in production (Supergirl, The Flash, Arrow, and Legends of Tomorrow). Whether Supergirl will move between universes and join Barry Allen and Oliver Queen in Earth-1, or will remain on a separate Earth, remains to be seen.
